What is log3 6 + log3 13.5

1 answer:

6 0

Log base3 (6*13.5)
log base 3 (81)
log base 3 (3)^4
4 log base 3 (3)
4 * 1 = 4

First condense the logs by using the product rule.
Next rewrite 81 in terms of 3.
Use the power rule and bring the 4 to the front.
log base 3 (3) = 1
Which leaves 4 * 1 = 4

A rectangle has an area of 96 sq ft if the width of the yard is 4 ft less than the length, what is the perimeter in ft of the ya

Veronika [31]

The area of a rectangle is obtained through the equation,

A = L x W

The width of the yard is 4 ft less than the length and may be expressed as L - 4. Length may be solved through the following steps,

A = (L)(L-4) ; 96 = L(L - 4) ; L = 12 ft

The length and width are 12 ft and 8 ft, respectively. Perimeter may be solved through the equation,

P = 2 x (L + W)

Substituting the values of L and W

P = 2 x ( 12 ft + 8 ft) = 40 ft

Therefore, the perimeter of the yard is 40 ft.
